Trend line case study of Starhub

I want to show you a case study based on another component stock in the Straits Times Index.

Back in July 2015, I observed that Starhub (CC3.SG) another blue chip company, broke a decade long trend line signalling a potential down move. At that time Starhub was trading at $3.95.

February 2016 I published a followup which correctly described Starhub’s recovery at that time as a pullback into resistance. Starhub was then trading at 3.56.

Starhub is trading at 2.78 today. Starhub is an example of getting the trend right based on trend lines only; where the trend lines are very long and prominent. Anyone who followed the trend line’s signal back in mid-2015 would have made a lot of money.


More questions for Yangzijiang

Back to Yangzijiang, timing won’t be easy especially when I am using monthly and weekly charts here. On hindsight everything looks perfect. When you actually do a position, you have deal with ups and downs every do. There is no perfect technique to time your trade precisely.

Those trend lines on the YZJ chart span from 2008 to present. That’s 9 years coming to 10 at the end of this year. That is almost as long as the Starhub trend line. So my question again is would you consider Starhub as a buying or selling proposition. Would you consider the trend lines or not?

The correct answer leads to a pot of gold. I want to know.
